流量控制和拥塞控制都是不同情况下的流量控制方法。
流量控制和拥塞控制之间的主要区别在于，在流量控制中，控制从发送方到接收方的流量。另一方面，在拥塞控制中，流量受到控制进入网络。
让我们看看流量控制和拥塞控制的区别：
| S.NO | Flow Control | Congestion Control |
|---|---|---|
| 1. | In flow control, Traffics are controlled which are flow from sender to a receiver. | In this, Traffics are controlled entering to the network. |
| 2. | Data link layer and Transport layer handle it. | Network layer and Transport layer handle it. |
| 3. | In this, Receiver’s data is prevented from being overwhelmed. | In this, Network is prevented from congestion. |
| 4. | In flow control, Only sender is responsible for the traffic. | In this, Transport layer is responsible for the traffic. |
| 5. | In this, Traffic is prevented by slowly sending by the sender. | In this, Traffic is prevented by slowly transmitting by the transport layer. |
| 6. | In flow control, buffer overrun is restrained in the receiver. | In congestion control, buffer overrun is restrained in the intermediate systems in the network. |
